Ultrafast Dynamics of Spin Current and Electron Temperature in Spintronic Terahertz Emitters

open access: yesAdvanced Science, EarlyView.
This work quantifies optical‐pump‐induced THz transmission variations to reveal electron and lattice temperature dynamics and presents time‐resolved THz spectral maps for sub‐picosecond analysis. A 63 ± 8 fs time lag between THz emission and laser excitation is identified, serving as an intrinsic parameter limiting the upper frequency of spintronic THz

PGK1 Suppresses CD8+ T Cell‐Mediated Antitumor Immunity Through CCL2/CCR2/Tumor‐Associated Macrophages Axis in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
PGK1 in tumor cells upregulates CCL2 expression through activation of the AKT/GSK‐3β/β‐catenin signaling axis, thereby promoting the recruitment and M2 polarization of TAMs and ultimately impairing the infiltration and activation of CD8+ T cells within the HCC tumor microenvironment. ABSTRACT Patients with advanced hepatocellular carcinoma (HCC) have a
